As you can see, there are some new links under each post. These links are so called ‘social bookmarks’ and they help other internet users find interesting news. If you have account on Digg, del.ico.us or such site, feel free to use this new feature. If you don’t know what it is about, read more about this topic on wikipedia.
If you use other system, let me know in comments, I can add it in an instant.
